It drops into the red and then the dinger starts sounding off. If I sit at the light with my left foot on the brake and apply a slight amount of throttle I can keep it out of the red. I put a small amount of sea foam in the oil to see if maybe something is gummed up in the oil pump.

5W-30 seems too thin of an oil for a non-supercharged engine. Last I knew, the N/A'* used 10w-30.

Sounds somewhat like what my 99 SE is doing...ever figure out the problem?

I have the same issue and noticed the oil cooler lines leak a little does anyone think this could ever effect the oil pressure like this

From the factory, the 3800'* do not have oil cooler lines installed.

Well unites there transmission cooler lines and oil is dripping on then from somewhere but there is a listing for them on rock auto

Unless there transmission lines not unites ha ha

No sir. That might be an add on kit accessory of some sort. And yes, they are available for the 3800'*, but I have never seen one installed or seen an actual parts listing for one in the GM books or field service manuals.

Weird because its going into the side of the radiator looks stock to me I will check tomorrow where it attaches to on the motor and take a pic

This is the gm pic of the tranny lines. The gm catalog does not show any oil cooler lines for this vehicle.
